Blender Startup Problem

When I start up blender, a message box pops up. It pops up ~15 times before opening the blender window, then pops up repeatedly afterwards. The box looks like this: http://i.imgur.com/Dc3Rtku.png

When I run blender with -d, the DOS box looks like: http://i.imgur.com/txDsdiq.png

Does anyone know why this is happening? I used to be able to run blender without problems.
